Data Sources and Citation Metrics
The 5th edition of the Research.com Best Microbiology Scientists in Cambodia Ranking leverages comprehensive bibliometric data primarily sourced from OpenAlex and CrossRef, supplemented by multiple additional reputable data providers. This diverse integration of databases ensures a broad and accurate representation of scientific output. The bibliometric data underpinning the citation-based metrics were meticulously collected on January 12, 2026, and form the foundation for determining each scientist’s position within the ranking.
Central to the ranking methodology is the use of the D-index (Discipline H-index), a refined bibliometric indicator that accounts solely for papers and citation metrics within the examined discipline. This focused metric allows for an accurate reflection of a researcher’s impact specifically within Microbiology, eliminating dilution from unrelated fields.
Scope of Research and Inclusion Criteria
The ranking draws upon an extensive examination of 187,659 scientist profiles across all scientific disciplines, ultimately identifying 1 leading scientist specifically in the field of Microbiology in Cambodia. To qualify for consideration, a scientist’s D-index must meet a minimum threshold of 40. Additionally, the majority of their tier publications must be verifiably within the Microbiology domain. Recognized awards and notable achievements in Microbiology constitute important supplementary factors evaluated alongside bibliometric measures.
The D-index threshold used to identify top researchers is calibrated in increments of 10 relative to the estimated total number of active scholars within each discipline. This calibration is designed to consistently incorporate the top 1% of leading scholars, ensuring an inclusive yet selective representation. Furthermore, to maintain disciplinary relevance, the ranking requires that the difference between a scientist’s overall H-index and their D-index does not exceed 30%.
Verification Practices and Methodological Rigor
Recognizing that raw bibliometric data alone can be insufficient to fully evaluate scientific contribution, the researchers behind this ranking implemented a rigorous manual verification process. Each scientist’s profile was carefully cross-correlated against publications indexed in a broad set of trustworthy sources, ensuring accuracy and reliability. While not a direct factor influencing ranking positions, the number of papers published in prestigious journals and conference proceedings is considered a valuable secondary signal of a researcher’s influence and productivity within Microbiology.
The final rankings are established exclusively using each researcher’s D-index, derived from data provided by OpenAlex and CrossRef—the most prominent and respected bibliometric databases widely accessible to the research community. This transparent and robust approach reinforces the credibility of the ranking. For an in-depth understanding of the full methodology, readers are encouraged to visit our methodology page.
